On Thursday 10 March traffic using Littlemoor Road will start to use the Bincombe Bumps Roundabout.
Also, from 12.30pm on Thursday, Icen Lane will be closed at the point where the relief road crosses it.
Vehicles and pedestrians coming from Bincombe or wanting to access Icen Farm from Dorchester Road will be directed to use Bincombe Bumps Roundabout and the new Icen Lane link road.
Temporary three-way traffic signals will still be in use at the east exit from the roundabout until the road tie-in work is complete.
Although the aerial image above is from January this year, it should give a good idea of how the road layout will change on Thursday.
